Installed on the main drain of your plumbing system or on the drain pipe, the check valve prevents the waste water from a municipal sewer to return in the basement. This protection is essential because, during heavy rains, the sewer system could backflow due to the pressure caused by a major accumulation of water. Without the check valve, a flood can cause a lot of damage and expenses in terms of repairs. Your home insurer may then hold you responsible for the proper functioning of your sanitary equipment.
A check valve is mandatory to prevent waste water and rain water from backflowing. To ensure that the check valve is appropriate and properly installed, the work must be done by a professional. Plomberie MALV offers an impeccable and certified service.
